Small thud when coming to a stop (Ecodiesel, 33 gallon tank)

[BDKC81]

Has anyone else experienced a small thud/bump immediately following a complete stop? I have a 2021 Ram Limited EcoDiesel, 3.21 gears and just started noticing this as I approach 40k. I've read that gas slosh was an issue in the last gen but haven't found much on the 5th gen. My tank is currently at 3/4 full and I'm noticing the thud. I can put the truck in neutral and roll to a stop and still replicate it so I do not believe it's the 2-> 1 downshift or transmission related. Also, if I come to a fast or very slow stop it does not seem to bump. I'm going to see what happens as the fuel level decreases but wanted to see if anyone could offer some thoughts. Thanks in advance.

I had the same problem with my 2022 RAM 1500 Limited. It turned out to be the driveshaft. Mine is a multi piece driveshaft with an expansion area under a protective sleeve. The slotted protected area gets dry from lack of grease and you will get a clunk when you stop. Dealer replaced my driveshaft rather than degrease the slots. Fixed the problem. There is a TSB on this from RAM for the REBEL model.

In a previous car, that was the main symptom when I needed new motor mounts.
